摘要： System, methods, and other embodiments described herein relate to safely ceasing fuel cell (FC) operation and idling components of a generator. In one embodiment, a method includes ceasing power generation by reducing fuel to an FC within a generator while maintaining energy to sensitive components by a battery. The method also includes idling a direct current (DC) converter and a load inverter associated with the power generation before idling the battery. The method also includes, upon successfully completing tests and powering down non-critical components of the generator, entering the generator into a standby status.

摘要： Described are systems and methods for directly monitoring the conductivity of the coolant used to regulate the temperature of a fuel cell. The system includes a coolant loop that acts as a conduit for the coolant, an ion exchanger configured to deionize the coolant, and a conductivity sensor configured to output an electrical signal indicating a conductivity of the coolant. The system also includes a processor in communication with the conductivity sensor and a memory having instructions that, when executed by the processor, cause the processor to determine the conductivity of the coolant based on the electrical signal from the conductivity sensor and determine when the ion exchanger requires servicing based on the conductivity of the coolant.

摘要： Systems and methods for monitoring the isolation resistance of one or more fuel cells are described herein. In one example, a system includes a current transformer having a hollow core. First and second portions of a load line from a fuel cell are located within the hollow core. The first portion of the load line is electrically between an anode of a fuel cell and an electrical load, while the second portion of the load line being electrically between a cathode of the fuel cell and the electrical load. The current transformer is configured to output an electrical signal proportional to a current passing through the hollow core. This electrical signal can then be used to determine the isolation resistance of the fuel cell.

摘要： System, methods, and other embodiments described herein relate to safely activating a fuel cell (FC) within a generator. In one embodiment, a method includes initiating a test for sensitive systems of a generator using backup power including a battery. The method also includes powering an FC and a direct current (DC) converter within the generator to an operational level using the battery, wherein the DC converter stabilizes a circuit fed by the FC. The method also includes, upon successfully completing the test and powering the FC and the DC converter, energizing a load inverter after completing a non-critical sequence that controls support systems of the generator, wherein the DC converter stabilizes energy between the FC, the battery, and the load inverter.
